MACHINAE FOR TRIIVIMING BARREL-HEADS.

SPECIFICATION forming part of Letters Patent ITO. 305,4:47, datedSeptember 23, 1884.

I I Application filed May 20, 1694. (No model.)

To aZZ whom it may concern:

Be it known that I, ADAM GUERDAN, a resident of New York city, in theconntyand State of New York, have invented an Improved Machine forTrimming the Edgesof Heads of Casks, of which the following is a full,clear, and exact description, reference being made to the accompanyingdrawings, in which Figure 1 is a plan or top view of my improved machinefor trimming the edges of the heads of casks. Fig. 2 is a side elevationof the same. Fig. 3 is an outer face view of the bevel-planer which isused on the machine. Fig. 4. is avertical transverse section of thecentral planer which is used on the machine. Fig. 5 is a verticaltransverse section of the machine on the line c, Fig. 1. Fi 6 is aninner face view of the finished head. Fig. 7

is an outer face view of one of the plates between which the head isclamped. Fig. 8 is a detail horizontal section of the bevel-planer, theline It 7c,-Fig. 3, indicating the plane of section. The'object of thisinvention is to produce a machine for trimming theedges of the heads ofcasks. are of heavy wood and bulging in formthat is to say, concave onone side and convex on the other and the periphery of such a head shouldbe trimmed so as to form bevel-edges along the concave and convex facesof the head and an intermediate straighter edge. instances these headsare, moreover, slightly oval, instead of circular, and my machine is toproducethe desired peripheral form of the head, when the same is ofeither circular or oval shape.

The invention consists, principally, in combining with a movablecarriage a set of planers for producing the two bevels and intermediatestraighter portion on the edge of the head, and also a set of clamps forholding the head in place, and means for rotating said head and alsosaid" planers, all as hereinafter more fully described.

The invention also consists in certain details of improvement, that arehereinafter more fully pointed out.

The heads of casks to which I refer In many and 6. Fig. 1 shows its edgeto have the bevels a and b and the intermediate straighter portion, d.Fig. 1 also shows that that face e of the head A which is inimmediatecontact with the bevel a is concave, while the other face, f,is slightly convex. This concavity and convexity of the head isobservable only when the head A is inspected inthe direction of thearrow 9, that is shown in Fig. 6, for on the line h '11, that is shownin Fig. 6, the head is concave on the face e and convex on the oppositeface, f. If, however, the head is inspcctedin the direction of the arrow3, Fig. 6, this concavity and convexity of faces no longer appear. Thisis made clear by the section of the head which is represented in Fig. 5,and which shows that on the line It Z, Fig. (3, the face of the head oneach side is perfectly straight. The face view, Fig. 6, also shows thatthe head A on the line ht is narrower than on the line it Z-in otherwords, that its periphery is slightly oval, with the longest diameter onthe line it Z. It is this kind ofhead, bulging and slightly oval, whichit is intended to trim in my machine so as to produce thereon the edgesa b d.

I will now proceed with the description of my machine.

B is the frame of the machine. In this frame is hung a shaft, 0,carrying at its inner end a disk, D. Another similar disk, E, faces thedisk D, and is carried by a shaft, F, which has its hearings in a hollowscrew, G, (see Fig. 5,) which screw turns in a nut, H, that is fixedupon the frame B. The said screw G has asuitable hand-wheel, I, oranalogous means for turning it by hand. The face of the disk D is of aconvex form, which will enable it to fit the concave face 0 of the headA. The face of the disk E is of a concave form, which will enable it tofit the convex face f of the head A. This is clearly represented inFigs. 1 and 5. Small screws m are held in the disks D and E, as shown.The shaft 0 connects, by a train of gear-wheels, a, or equivalentmechanism,with a driving-shaft, J, that has itsbearings in the frame B,and to which rotary motion is imparted by suitable mechanism, so thatthe shaft 0 will be turned quite slowly when the machine is inoperation.

ward the shafts G and F. In the carriage L are the bearings of a shaft,P, which is parallel with the shafts CF, and nearly on the same planetherewith, as indicated in Fig. 2. The shaft P connects, by a belt, Q,or otherwise, with suitable mechanism, by which very rapid rotary motioncan be imparted to it.

and 5.

the disks.

The shaft P carries the cutter-heads for three sets of planersthat is tosay, a truncated conical cutter-head, R, which carries theplaning-knives a in oblique position. Contiguous to the smaller end ofthis cutter-head R is the cutter-head S, (see Fig. 4,) of prismaticform, carrying the straight knives d. Contiguous to this, again, isthesmaller end of a truncated conical or slightly-spherical cutter-head,T, into which are set the oblique cutters b". (See Figs. 3 andS.) Y

The operation of this machine is as follows: The head A to be trimmed isplaced between the disks D and E, so as to fit the samein the propermanner, which is indicated in Figs. 1 The screw G is then turned tocrowd the disk E against the head A, and thus clamp the head firmlybetween the disks D and E. The screws m are then turned to bite the headA and insure its due retention between said disks.

, /But I desire it to be understood that the screws m can be dispensedwith, or equivalent prongs or ribs formed on the inner faces of It willbe seen that when the disk is thus held in position it is aligned withthe cutters that are carried by the shaft P, in such manner that whensaid cutters are brought against the edge of the head, by moving thecarriage L, and the shafts G, F, and P revolve, the cutters a willproduce the bevel-edge a, the cutters d the straighter edge (I, and thecutters b the bevel-edge b, which latter edge may be slightly concave,as show-n. Inasmuch as the head A will be revolved very slowly, whilethe shaft P will be revolved with great rapidity, the attendant willhaveit under his control to produce the oval outline'of the head A bymoving the carriage L at the propertime farther toward and then fartheraway from the shafts Q and F. The relative speed which I find to bedesirable in such a machine is about one revolution of the shafts O Ftotwelve hundred of the shaft P. The gage 0 will prevent the carriage Lbeing slid nearer to the shafts O F than is necessary for the smallestportion of the diameter of the head A to be shaped.

To my knowledge, heads of the kind described could heretofore only betrimmed by hand, because of the great irregularity resulting from theconcavo-couvex shape of the head, and from its oval circumference. Thesepeculiarities of shape, it will be seen, cause the bevel-edges a and bto vary in widthin different portions of the head, as is shown in Figs.1 and 6. The face of the disk D, it will be seen, is practicallycylindrico-convex, and

that of the disk E cylind rico-concave, in order to cause these disks tomatch the concavo-convex head A. l

I claim 1. The combination of the shaft 0, carrying the convex disk D,with the shaft F, carrying the concave disk E, hollow screw G, surrounding the shaft F, movable carriage L, cutterheads R S T, cutter-shaft P,and means, substantially as described, for revolving the shafts G and P,all arranged for trimming the edges of an irregularly-shaped head, A,for a cask, substantially as described.

2. The shaft 0, carrying theconvex disk D, combined with mechanism, asdescribed, for

revolving it, and with the concave disk E,held

on the shaft F, which is surrounded by the hollow screw G, all arrangedfor clamping a head, A, between said disks D E, and with the cutter R ST, as specified.
